Frontal view:
- loss of parallelism of the first and second carpal arcs of Gilula
- the radiolunate articulation is widened
- advanced degenerative arthritis in the radioscaphoid and capitolunate articulations
- collapse of mid-carpal joint
Lateral view:
- loss of alignment radius-lunate-capitate-3rd metacarpal
- dorsal tilting of the lunate with dorsal subluxation of the capitate
- the findings are compatible with a dorsal intercalated segmental instability (DISI) deformity
